NIPPON KINZOKU<\/a> CO., LTD. (Headquarters: Minato-ku, Tokyo) announces the launch of a sample supply system for its \u201cInternally Polished Capillary Tubes.\u201d<\/p>\n

These tubes feature significantly enhanced internal smoothness in ultra-small sizes, realised through the development of the company\u2019s proprietary internal polishing technology.<\/p>\n

We are currently proceeding with the design and construction of manufacturing equipment, aiming for mass production within fiscal year 2027.<\/p>\n

Background: Rising Demand for \u201cUltra-Small Diameter x Ultra-Smooth Internal Surfaces\u201d<\/p>\n

We have previously developed high-precision, small-diameter tubes made of austenitic stainless steel with an internal diameter (ID) of 0.50mm and internal surface roughness of \u2264 0.5\u03bcm, which have been highly evaluated across various industries.<\/p>\n

In recent years, the advancing performance of analytical, medical, and biotechnological equipment has driven a rapid surge in demand for capillary tubes with even smaller diameters and smoother internal surfaces. To achieve a level of internal roughness in the 0.30mm ID class that was previously unattainable through conventional manufacturing methods, we have established our proprietary internal polishing technology.<\/p>\n
